Regulatory Compliance and Safety Information

Cisco DMS Overview

Cisco Digital Media Suite (Cisco DMS) is an ecosystem for networked digital video. It is also the collective name for a broad range of hardware products, software products, and accessories. We sell and license these separately but they work together seamlessly.

Cisco DMS is a key component of several Cisco portfolios. To learn about the full range of Cisco DMS products and technologies, see http://cisco.com/go/dms.

DMP Overview

Cisco Digital Media Players (DMPs) are highly reliable, compact, solid-state devices for IP networks. DMPs process High Definition and Standard Definition video, multimedia and animations, web pages, and other supported content types for playback. You expose targeted audiences to this programming when you schedule its playback — live or on demand — on a public presentation system that is attached to a DMP. This presentation system might be a display (monitor), touchscreen, video projector, or video wall.

DMP 4305G

DMP 4310G

DMP 4400G

DMPs consume very little power and are designed for fast deployment throughout IP networks of any size, without the burden of high ongoing operational cost. And thoughtful use of Cisco Medianet technologies can make DMP deployments faster and simpler than ever before.

DMPs are compatible with popular systems for networked content distribution, including Cisco Enterprise Content Delivery System (ECDS), Cisco Application and Content Networking System (ACNS) and Cisco Wide Area Application Services (WAAS).

Any two DMP models will differ in their features, attributes, strengths, limitations, and general availability. Some DMPs differ from others, for example, in their support for interaction through touch. To learn what your DMP supports, see its datasheet at http://cisco.com/go/dms/dmp/datasheets.

DMPs are a major component of Cisco Digital Media Suite (Cisco DMS) and Cisco StadiumVision, both of which we describe elsewhere in this guide.

DMPDM

A lightweight webserver on every DMP runs a web-based "craft interface" called Digital Media Player Device Manager, or DMPDM. Because DMPDM is limited to the simplest functions and does not scale beyond its own host DMP, we recommend that you manage all DMPs centrally.

DMPDM has two main purposes. With it, you can:

•Configure one DMP during its initial setup.

•Manage one DMP and one presentation system in isolation. (Or, when you use signal splitters or daisy chaining, your DMP can deliver media to multiple presentation systems that are close to it — as would be the case with a video wall.)

Note StadiumVision deployments should avoid using DMPDM, except to check the firmware's "build date" or release version number. For other tasks, please use the management dashboard software and documentation that came with your StadiumVision purchase.

You cannot install browser plug-ins or any other software in TVzilla, whether to support additional file types or for any other purpose. No Java Runtime Environment is installed.

Cisco Hinter

A technique called interleaved RTP makes it possible for some centrally managed DMPs to play delay-insensitive unicast MPEG streams through RTSP connections. A streaming server can then transmit this "hinted" video to DMPs on demand. The key advantages of interleaved RTP are that data loss is impossible inside the hinted program stream, and yet synchronization of audio to video never suffers, even in high-definition.

Cisco Hinter is software to prepare and stage MPEG files for interleaved RTP transmission through the open source Darwin Streaming Server component on a Cisco Digital Media Manager (DMM) appliance.

Note Thus, this utility and this feature are not available in deployments that use Cisco StadiumVision. There is no DMM appliance in StadiumVision.

Cisco Hinter versions for Windows and Linux users are freely downloadable from any DMM appliance that is fully licensed for Cisco Digital Signs. To understand Cisco Hinter and Cisco Digital Signs fully, see the DMM user guideon Cisco.com.

Optional DMP Accessories

Note We reserve the right to introduce, redesign, or discontinue any accessory as needed.

We have designed optional accessories to enhance your DMP experience. For example, you might order handheld remote control units or VESA-compliant mount kits.

Remote Controls

Cisco sells handheld remote control units that you can use to operate DMPs. We sell these optional remote control units separately to conserve natural resources and prevent needless waste.

•Consult the remote control datasheet to learn exactly the maximum distance from which your remote control can control your DMP.

•To order remote controls, contact your Cisco sales partner.

•Remote control documentation is available on Cisco.com.

Mount Kits

Cisco sells fabricated sheet metal cases to stabilize and protect Cisco DMPs in any supported mounting scenario. With these cases, you can mount DMPs securely to walls, pillars, suspended-grid ceiling T-joints, metal poles, or VESA-compliant flat-panel displays. DMP mount kits are a versatile and cost-effective alternative to complex cabinet-making and construction projects. They do not block ventilation or heat dissipation.

Plan and Prepare

Consider How You Will Use and Manage Your DMP

Tip Cisco Medianet technologies can help you to manage the DMPs in your network. To understand DMP support for Medianet, see User Guide for Cisco Digital Media Suite on Cisco.com.

An organization might buy and use one DMP in isolation but this is rarely the case. Almost every DMP is part of a network that includes many other DMPs.

The ideal DMP management system (or combination of systems) for your organization depends on how many DMPs you have and how you plan to use them. Beyond this, a management system might impose its own installation and setup requirements for DMPs.

Topics in this section describe Cisco products to manage DMPs in various settings.

Manage One DMP in Isolation

Centrally Manage Digital Signage Services

Cisco Digital Signs provides a flexible environment in which to create and centrally manage a local, regional, or global IP network of DMPs and their attached presentation systems — such as Cisco-branded displays in our LCD Professional series.

•Simple but powerful design and publishing features in Digital Signs help you to create media libraries, employ networked content distribution, schedule playback for programming, and prepare reports to prove that playback occurred.

•Life-saving features support public emergency preparedness and response.

•Purely administrative features help you to manage DMPs and their attached presentation systems.

Centrally Manage IPTV Services

Cisco Cast features help your organization to deliver video-on-demand and live broadcast TV channels over a local, regional, or global IP network of DMPs and their attached presentation systems — such as Cisco-branded displays in our LCD Professional series.

•Browse or search with interactive on-screen menus and program guides.

•Show live or on-demand:

–news

–financial information

–sales and marketing messages

–educational or instructional media

–corporate communications

–entertainment

–any other video asset that is suitable for your purpose

•Alternatively, hospitality and healthcare providers might use Cisco Cast features to support in-room IPTV.

Centrally Manage Sports and Entertainment Venue Services

Cisco StadiumVision is an advanced solution for centralized IPTV video content management and delivery. It integrates video from multiple sources — in Standard Definition (SD), High Definition (HD), or both — to automate video delivery in stadiums, arenas, and similar venues.

Platform services software and control panels help you to manage a network of DMPs. Combined with Cisco video acquisition infrastructure at the head-end, these DMPs use new or existing video displays in a venue to enhance patron enjoyment of live events and deliver in-house advertising. Your deployment can leverage the displays in bleachers (terraces), restaurants, clubs, and luxury suites to deliver a range of uniquely interactive messages automatically to patrons in various areas.

With StadiumVision, you can add, organize, combine, and deliver any supported combination of in-house programming and external network channels for playback to your patrons.

Qualify a Location for Setup

Cable length, signal strength, and other factors limit where you can set up a DMP — relative to the location of its AC power source, its presentation system, and any person on site who will use a remote control to operate the DMP.

Site-Specific Conditions

Assess each location where you might want to use this equipment.

Adequate Shelter

Install and use this equipment indoors — or outdoors in a covered area.

•Never install or use it in a wet environment.

•Never install or use it near radiators, open flames, or other heat sources.

Supported Voltage

There are — at most — only two supported methods to power this equipment.

•Use the standard electrical power cord that came with the equipment. Cord length determines the maximum possible distance from the equipment to any AC electrical outlet that it can use. The outlet itself must use standard voltage for your locale, within the range from 100V to 240V. We recommend that you use a surge suppressor, line conditioner, or uninterruptable power supply (UPS). Please position all cables and power cords carefully. Route all cables, the power cord, and the plug so that they cannot be stepped on or tripped over. Never allow anything to rest on equipment cables or cords.

OR

•Use 802.3af power over Ethernet (PoE), assuming that your equipment model supports this feature. We describe PoE setup elsewhere in this guide. To learn if your equipment model supports this feature, see its datasheet at http://cisco.com/go/dms/dmp/datasheets.

DHCP
Access

Each new DMP (and each DMP on which you restore factory-default settings) uses DHCP to obtain its first IP address. Therefore, a DHCP server must be reachable from the site where you set up a DMP. Later, after your DMP is fully configured, it can use either static or dynamic IP addressing.

Signal Integrity

When physical cables are too long, the signals that they carry can degrade. Signal loss can also affect wireless connections — including the infrared connection between a DMP and its remote control. When signal integrity suffers, equipment performance suffers.

Unpack the Equipment

Check Package Contents

The shipping container that you received contains your equipment product kit. This kit contains a printed packing list. Compare the packing list to the kit. The packing list tells you how to request a replacement if anything is missing from the kit, is defective, or is damaged.

Note Do not discard or recycle the printed packing list. You will use it.

Start to Keep Records Now

Before you recycle or discard the shipping container that you received, examine it. Then, write down or photograph any important information that is:

•Printed directly on the shipping container.

•Printed on any material that is affixed or fastened to the shipping container.

This information might help you to obtain warranty service, replacement parts, or technical support if you ever need them.

2Category 5 or better. Maximum length: 328 ft (100 m). For any distance greater than 165 ft (50 m), we recommend that you use Category 5e or Category 6 certified Ethernet cabling. For installation behind walls, we recommend plenum-rated cabling unless it does not satisfy the requirements set forth in your regional building code. We do not ship any Ethernet cable with any DMP model. You must obtain this cable separately.

DMP 4310G Notice Regarding Power over Ethernet (PoE)

Starting in 2009, a handful of Cisco StadiumVision customers participated in a special program to receive DMP 4310G endpoints whose hardware design was not yet utterly final. During this limited, pre-release program, we manufactured such units under the Cisco product ID "DMP-4310G-SE-K9." Partway through the limited release, we changed one physical component in the hardware design to improve the Power over Ethernet (PoE) performance of a DMP 4310G.

When even one of these statements is true, your DMP 4310G uses the improved PoE component. Nothing further about this topic applies to you or your DMP.

Otherwise, when even one statement is false, your DMP 4310G uses the original PoE component. We have identified a corner case in which these DMPs might not receive full PoE power. Suppose that a very long Ethernet cable connects the DMP 4310G to a network switch from the Cisco 3560 Series. And suppose also that the Ethernet cable length is so great that the level of PoE power becomes noticeably diminished after traveling its full distance to the DMP. In this scenario, your DMP cannot compensate for the degraded power because switches in the Cisco 3560 Series do not permit adjustments to their PoE power output.

We recommend that you do not obtain power for such DMPs from network switches in the Cisco 3560 Series. When you must do so, then take care to use the shortest possible Ethernet cord. Alternatively, you might use network switches from the Cisco 3750 Series, which offer configurable PoE power output.

Electrical Power Source Procedures

Connect to a 100V-240V AC Socket

Warning Use ONLY the power adapter, power cord, and plugs that we supply for your DMP model explicitly. DO NOT USE OTHERS, even if they appear identical or appear to work with another DMP model.

Before You Begin

•Did your Cisco equipment ship with a power cord and AC adapter? Or did it ship with an AC adapter and multiple, snap-on plugs? Your packing list states which supplies Cisco planned to ship. (Alternatively, you might have purchased a Cisco power cord and AC adapter as accessories for your equipment.)

Use 802.3af Power over Ethernet (PoE)

Note•You can power a DMP 4310G through its Ethernet cable. Other DMP models do not support this feature.

•A DMP 4310G has two USB interfaces on its chassis. When you use PoE to power a DMP 4310G, we recommend that you use no more than one of these USB interfaces at a time. IEEE 802.3af PoE is limited in its capacity and might not be sufficient to power your DMP and two USB peripherals simultaneously.

•When both PoE power and AC power are detected, AC power overrides PoE and disconnects the PoE circuit.

Procedure

Step 1 Use the On/Off power button on the DMP chassis to verify that your DMP is turned Off.

Step 2 Connect a standard, Category 5 Ethernet cable to your DMP.

Step 3 Attach the other end of the Ethernet cable to a PoE-enabled network switch that operates inside your network.

Step 4 Use the On/Off power switch on the DMP chassis to turn your DMP On.

Medianet Glossary

A collection of interface-level switch commands bundled together as a macro that configures a switchport without human intervention. Upon detecting a connection to one of its physical interfaces (or "ports"), a
Medianet-ready switch uses
CDP packets or a similar mechanism
2 — in tandem with a
port-based network access control (PNAC) standard such as 802.1x/MAB — to learn what type of device has connected to it. Device identification triggers the appropriate Auto Smartports macro to run automatically on the switch and configure its interface appropriately for the detected device type. This behavior eases the administrative burden of configuring multiple switchports manually. (Similarly, when there is a "link-down" event on the port, the switch removes the macro.)
In the ITU model and framework for network management, known as
FCAPS, Auto Smartports macros act in support of what's called
configuration management.

Cisco Discovery Protocol. DMPs and other devices that support CDP can communicate facts about themselves, amongst themselves, over any physical network medium that supports
Subnetwork Access Protocol (SNAP) encapsulation. CDP uses the
data link layer, which connects physical network media to upper-layer protocols. And because CDP operates at this level, two or more CDP devices that support different network layer protocols (for example, IP and
Novell IPX) can learn about each other.

Specifically, CDP causes devices to advertise not only their existence, but also their platform types, protocols, IP addresses, and SNMP-agent addresses to neighboring devices on their LAN switch or WAN. And when their connected switch is Medianet-ready, device identification
can also trigger
an
Auto Smartports macro to run automatically.

Thus, CDP facilitates discovery — by network management applications — of Cisco devices that are neighbors of known devices. And this is particularly useful when such previously undiscovered neighbors use lower-layer, transparent protocols. After they possess information about such devices, network management applications can send SNMP queries to them.

In turn, a DHCP server that is configured to support Option 125 can relay the client-generated request to some other DHCP server. This mechanism allows an organization to designate
DHCP servers for clients that meet particular criteria. For example, you might want all of your DMPs to receive their IP addresses from a
DHCP server that you reserve for this purpose exclusively.

Mechanism by which a device can learn its actual physical ("civic") location through its connection to a Medianet-ready switch. Upon learning its location, the device can then share this information with peers,
management servers, and other equipment on its network. The physical location of a DMP is almost always an important factor in which central management server it should trust, which assets it should play, which commands it should run, and which schedule it should follow.

Someone must configure two essential values on your Medianet-enabled switch: "
civic-location-id" and "
additional-location-information." These values are encapsulated into a CDP message that endpoints receive.

civic-location-id

This value describes the physical site — including the municipality, street address, floor designation, and so on — where a switch and its attached nodes are deployed.

additional-location-information

This value describes any additional details to inject into the encapsulated CDP message. As this is a data injection, it depends wholly on the presence of a defined civic-location-id value. Absent that value, there is no way for this value to reach any endpoint. Later, when you plug a Medianet-ready DMP into a properly configured switch, the Location Services feature of MSI populates the Location URL field automatically in DMPDM.

Note CDP and LLDP constrain how much location information you can store on a Medianet-enabled switch. Make sure that this information never exceeds 255 bytes.

Note A DMP 4400G cannot receive or use Location Services information over Wi-Fi. Its connection type to your Medianet-enabled switch must be Ethernet.

End-to-end intelligent architecture for optimized delivery of rich media to a variety of endpoints throughout an enterprise. Cisco Medianet is media-aware, endpoint-aware, and network-aware.

MSI

Media Services Interface. Announces services to a DMP or any other Medianet-ready device that you connect to a Medianet-enabled switch. MSI tells devices about their neighbors and their civic location.

MSI registration service

Medianet feature
by which:

•Devices send encrypted registration requests to management servers.

•Servers receive such requests, respond to them, and store records in a local database.

MSI service discovery

Mechanism that applies DHCP option 125 packets to advertise — and poll for — the availability of particular services in a network. Service Discovery also notes which hosts provide these services. For your purposes as a DMP administrator, Medianet should know that a DMM server is available and know exactly which addressable node it is on your network. So naturally, you must configure your DHCP server to facilitate this information-sharing model. Configuration methods vary among platforms and implementations. An example here shows entries in the dhcpd.conf file for a Linux-based DHCP server called dhcpd. Entries like these advertise the IP address of your authoritative DMM appliance — converted here from decimal to hex and shown in red — to any DMPs that should trust its directives implicitly.

In contrast, the DHCP offering in Windows Server 2008 (and, likewise, Windows Server 2003) cannot handle DHCP option 125 queries natively. Therefore, you must install a "callout" DLL that injects this ability into the server before you can configure it to advertise the availability of any service.

Note For 32-bit Windows Server, the DLL filename is DHCPSDDLLx86.DLL. For 64-bit Windows Server, the DLL filename is DHCPSDDLLx64.DLL.

Afterward, you must edit \Medianet\msi\apps\dhcpsddll\src\dhcpsdconfig.reg to include a 3-tuple (IP,port,transport
), converted to hexadecimal, that identifies your DMM appliance as a provider of centralized management for DMPs.

And finally, you must add two keys to the Windows registry, under \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCPServer\Paramters ·
CalloutEnabled REG_DWORD 1 ·
CalloutDlls REG_MULTI_SZ <full_path_to_DLL>

Note See the Medianet documentation on Cisco.com for detailed instructions.

Partial Support for Cisco Medianet 2.1 Features

Cisco Medianet is an end-to-end architecture for networks that deliver rich-media experiences. Some DMP endpoints support some Cisco Medianet 2.1 features.

DMP 4310G endpoints support discovery via DHCP and can learn their physical location. In addition, they know and can broadcast their product type, model, and software version. Through their use of your Medianet, they can receive their IP address, VLAN assignment, and network configuration settings automatically.Furthermore, they receive information from Medianet through DHCP1 that helps them to autoregister themselves with your DMM server. Later, after a successful autoregistration, the splash screen on these DMPs includes key parameters and states explicitly that setup succeeded.

DMP 4400G

Medianet 2.1 feature support by DMP 4400G endpoints is equivalent to support by DMP 4310G endpoints, with just one exception. Ordinarily, a DMP 4400G can participate in networks via either an Ethernet connection or a Wi-Fi connection. However:

A Wi-Fi connection by a DMP 4400G prevents it from obtaining or using any Location Services information that Medianet might be configured to provide.

1With DHCP option 125 (V-I Vendor-Specific Information) for service discovery, after you configure your supported DHCP server to support this option. See RFC 3925.

Note These features are designed to simplify the largest deployments, whereas DMPDM is designed to support the smallest deployments. If you manage your DMP primarily via DMPDM, your benefit from Medianet integration will be minimal.

Understand Medianet Autoconfiguration for DMP 4310G Endpoints

DMP 4310G and 4400G endpoints can use CDP to announce and identify themselves on networks.

ANDYou might use Ethernet cables to connect such DMPs to switches where the autoconfiguration (Auto Smartports) features of Medianet are enabled.

When you do, these switches recognize from the CDP announcements that the newly connected devices are DMPs.

After recognizing that a DMP is attached to one of its Ethernet ports, the switch can apply to this port a set of built-in configuration macros (Auto Smartports) that are optimized specifically for DMPs. By configuring so many settings automatically, Medianet can accelerate and simplify DMP mass deployments, QoS configuration, and asset tracking. In turn, these simplified deployments can lower your operating costs.

Medianet Restrictions

When a DMP 4310G relies upon a Medianet switch where more than one VLAN uses DHCP, the DMP might come to use the wrong IP address. For this to occur, temporary conditions that do not sever the DMP's AC power connection must nonetheless interrupt its network connection through the switch. (Thus, this problem cannot possibly occur while the DMP uses PoE.) Specifically, the Medianet switch assigns its default VLAN to your DMP. But then — after your DMP's network connection is interrupted and restored — your Medianet switch assigns to your DMP a dynamic IP address from another VLAN on your Medianet switch. This easily prevented mismatch disrupts centralized management of your DMP. To prevent this problem or to recover from it, you can download and run the patch from Cisco.com.

Understand Whether the IP Address Will Be Static or Dynamic

The factory-default behavior for every DMP is to obtain and use a dynamic IP address from a DHCP server in its local network segment.

Nonetheless, your DMP must have an IP address — even when you will deploy it where the local network segment does not include any DHCP server among its nodes. In this case, you must configure your DMP before you deploy it. This technique is sometimes called a green field deployment. The configuration steps differ in Ethernet and wireless networks.

Ethernet Connection Procedures

Establish an Ethernet Connection

Before You Begin

•Does a security policy in your network restrict DHCP address assignments to known MAC addresses? If so, locate the MAC address printed on a sticker that is affixed to your DMP. Then, share this address with your security policy administrator.

•Does your DMP support wireless networking? If so, consider whether you might prefer to use that method instead of this one.

Procedure

Step 1 Plug one end of a standard Ethernet cable into the corresponding interface on your DMP.

Step 2 Plug the other end of this cable into a network hub, network switch, or router whose network uses DHCP to allocate IP addresses dynamically.

AES-CCMP is a symmetric block cipher that can encrypt and decrypt data using keys of 128, 192, and 256 bits. It is based on the Advanced Encryption Standard (AES), as defined in the National Institute of Standards and Technology's FIPS Publication 197. AES-CCMP is superior to WEP encryption and is defined in the IEEE 802.11i standard.

Service Set ID. A unique identifier that client devices use to associate with the access point. The SSID helps client devices distinguish among multiple wireless networks in the same vicinity. The SSID can be any alphanumeric entry up to 32 characters long.

Caution Whenever you change SSID settings for your WLAN, your DMPs will lose their wireless network connections. After they are disconnected, they cannot reconnect automatically. In this case, an affected DMP will appear to associate to your WLAN access point but will not receive any IP address.

Wired Equivalent Privacy is a method to encrypt data transmitted on a wireless network.

WEP keys

Wired equivalent privacy (WEP) keys are the IEEE 802.11b standard that offers a mechanism to secure wireless LAN data streams. The goals of WEP include access control to prevent unauthorized users who lack a correct WEP key from gaining access to the network, and privacy to protect wireless LAN data streams by encrypting them and allowing decryption only by users with the correct WEP keys.

WPA

Wi-Fi Protected Access. WPA is a standards-based, interoperable security enhancement that strongly increases the level of data protection and access control for existing and future wireless LAN systems. It is derived from and will be forward-compatible with the upcoming IEEE 802.11i standard. WPA leverages TKIP for data protection and 802.1X for authenticated key management.

Wi-Fi Workflow

It is not necessary, useful, or correct to restart a DMP immediately after you define its 802.11 settings. Instead, the typical workflow is as follows.

1. Define wireless settings.

2. Savewireless settings.

3. Apply wireless settings.

a. Use DMPDM to restart the DMP.

b. Immediately unplug the DMP Ethernet cable.

OR

a. Unplug the DMP power cord.

b. Unplug the DMP Ethernet cable.

c. Plug in the DMP power cord.

4. Get WLAN IP address.

Understand WEP Keys and Passphrases

Timesaver Does your wireless network use WPA instead of WEP? If so, you can ignore this topic.

Many 802.11 access points (wireless routers) accept only a hexadecimal passphrase for WEP-64 and WEP-128. And yet, DMPs accept only an ASCII passphrase for WEP. For this reason, it might be necessary at times to translate your WEP passphrase from ASCII to hexadecimal. Many third-party converters are available. We do not offer any Cisco converter for this purpose.

The typical WEP process is as follows.

1. Pick an ASCII passphrase. For example, PassphraseWEP128.

2. Convert your string of ASCII characters to the hexadecimal key or keys for your network.

•WEP-64 uses four short hexadecimal keys.

•WEP-128 uses one long hexadecimal key.

3. Configure your DMP to use the ASCII from which you derived the hexadecimal.

4. Configure your wireless router to use the appropriate hexadecimal key or keys.

DMP 4400G Notice Regarding Wi-Fi Connections

Note You can configure wireless network settings during a later phase of DMP setup, if your DMP supports this feature. However, there are other tasks that you must finish first. When you are ready to configure wireless settings, these topics say how.

Connect to a Presentation System

A DMP transmits signals to a public presentation system that you choose, such as a flat-panel display or projector that is connected to the DMP.

•This system might use projection or display technologies that are analog or digital.

•It might support Standard Definition (SD) or High Definition (HD).

•Its output fidelity depends in part upon which signal cables (and adapters) connect it to your DMP.

Tip A feature of Cisco Digital Signs can detect automatically when some display brands and models are turned On or Off. To connect one of these displays to your DMP, you must use a null RS-232 serial cable in addition to the video signal cable. Cisco Digital Signs documentation on Cisco.com explains how to use this feature in your network.

Topics in this section teach you about these presentation systems, signal cables, and adapters.

Understand Which Displays Work Best with DMPs

We certify that DMPs work as designed with Cisco LCD flat-screen displays. All displays in this series are engineered for intensive use in public settings. See http://cisco.com/go/dms/lcd.

In most cases, DMPs can use displays that comply with modern, international standards. We recommend the following if you use a third-party display.

•Digital, not analog.

•High-definition, not standard-definition.

•Professional-grade, not consumer-grade. Digital signs and public IPTV installations run many more hours each day than a consumer-grade display is engineered to run. A consumer-grade system is likely to fail years sooner than a professional-grade system would under these conditions.

•LCD, not plasma. Digital signage uses static images more often than it uses full-motion video. Most often, content is web-based or animated in Flash. The nature of these media types means that some pixels are not updated frequently in digital signage. LCDs are less susceptible to burn-in than plasma displays are. Even though image persistence is sometimes a problem on LCD displays, it is almost always self-correcting and is unlikely to occur when you follow manufacturer guidelines for managing your displays correctly.

•Built-in support for RS-232 signalling. This recommendation is important in direct proportion to the number of displays that you will manage.

Special considerations apply when you obtain a signal cable that is longer or of a different type than cables that we included in your product kit. For DMP models that support the following signal cable types, the maximum supported lengths are:

•Composite — 10 ft (approximately 3 m)

•HDMI — 16 ft (approximately 5 m)

•RCA — 10 ft (approximately 3 m)

•S-Video — 10 ft (approximately 3 m)

•SPDIF — 10 ft (approximately 3 m)

Cable Quality

The best signal cables objectively are those with the lowest signal resistance. Factors that affect signal resistance include wire gauge, cable shielding quality, and cable connector quality. However, the same materials and engineering designs that reduce signal resistance add to the cost of manufacturing. This added cost is passed along to a consumer. So, it is useful to understand when signal resistance is not relevant. Knowing this can help you to manage and reduce expenses without necessarily lowering your standards. High cost is not inevitable. Nor is it proof of high quality. Sometimes, in fact, high quality (low signal resistance) is irrelevant.

Even mediocre signal cables are sometimes sufficient, and such cables are often very affordable. Figure 1 illustrates the most important factors to consider when you choose signal cables.

Figure 1 Signal Cable Purchasing Factors to Consider

Beyond the general guidelines that Figure 1 illustrates, two additional factors might constrain which types of signal cable you can use.

•The technology, brand, and model of your display — Check its product documentation to understand its compatibility with various signal cable types.

•The DMP model — Table 2 states which I/O ports are available on various DMP models. Alternatively, if the table does not describe your DMP model, see its datasheet at http://www.cisco.com/go/dms/dmp/datasheets. Your packing list states which signal cables Cisco planned to ship with your DMP.

Work Around the Low Signal Quality of Composite Video Cables

Note When image signals are transmitted through a composite cable, image quality suffers. When you use a composite cable and your DMP shows any web-based media, small text might be difficult to read in TVzilla. To work around this limitation, you can lower the browser resolution setting in DMPDM.

Understand How HDMI and DVI Differ

Other such systems might not connect until you combine the HDMI cable with an HDMI-to-DVI adapter for video. However, DVI does not support the transmission of audio signals. In this case, you can use the provided audio cable for audio.

DMP 4310G Notice Regarding HDMI/DVI Effects on Autodetection

A manufacturing error in your third-party presentation system might cause your DMP to render visual assets at an unexpectedly low-resolution for playback. This can occur when all of the following statements are true for you simultaneously.

•Your DMP model is 4310G.

•Your presentation system's media signal interface is DVI, not HDMI.

•EDID data in the firmware for your presentation system misrepresents its native resolution.

•The falsely claimed resolution is an HDMI standard instead of a VESA standard.

In this case, your DMP 4310G proceeds as if the native resolution is low, to ensure that your digital sign shows anything at all.

Tip This constraint does not affect a DMP 4305G or a DMP 4400G. These models do not use the same microprocessor that a DMP 4310G uses.

To work around this behavior, disable the autodetect feature in DMPDM and then choose the actual resolution manually.

Understand S-Video Limitations

When you use an S-Video cable to pass High Definition video signals to a DMP, the picture quality is not High Definition. This happens because the S-Video standard is engineered to pass analog video signals in Standard Definition.

When you will use an S-Video signal cable, we recommend a maximum resolution of 728 x 576 @ 25Hz and a maximum cable length of 10 feet (approximately 3 meters).

Use a Connection that Combines HDMI with DVI

HDMI and DVI differ in their support for audio signals and use connectors that are shaped differently, but otherwise are identical. Thus, an adapter can help you to connect to your DMP any presentation system that supports DVI but not HDMI. When you do this, however, you must also use a separate signal cable to transmit audio signals, or there will not be any audio.

Before You Begin

•Obtain an HDMI-to-DVI adapter.

Procedure

Step 1 Make connections for video.

a. Connect the HDMI cable to the HDMI interface on the back panel of your DMP.

b. Fasten an HDMI-to-DVI adapter to the free end of the cable.

c. Connect the free end of the DVI adapter to the corresponding interface on your presentation system.

Step 2 Make connections for audio.

a. Plug the 3.5mm audio jack into the Audio interface on the back panel of your DMP.

b. Connect the other end of the audio cable to the corresponding interface on your presentation system.

Step 3 If the presentation system is not already turned on, turn it On now.

Connect to a Touchscreen

Tip Some touchscreens work as designed only after they are calibrated manually. If your touchscreen is one of these, its calibration occurs during a later stage of DMP setup. The list of related topics for this procedure states where you can learn about calibration.

DMP connections to a touchscreen are similar to connections for other digital displays. However, touchscreens employ a special cable that supports interactivity through touch. This might be either an RS-232 serial cable or a USB cable, depending on the touchscreen model. Although some models support both cable types for interactivity, you can use only one type at a time.

•Check the documentation for your touchscreen to learn whether it requires a serial connection or a USB connection to your DMP, or if it supports both.

Procedure

Step 1 Connect an HDMI cable to the HDMI interface on the back panel of your DMP.

Step 2 Connect the other end to your touchscreen.

OR

If your touchscreen supports DVI connections and not HDMI connections:

•Fasten an HDMI-to-DVI adapter to the free end of the cable.

•Connect the free end of the DVI adapter to the corresponding interface on your touchscreen.

Tip You can use an HDMI splitter or other supported method to attach multiple presentation systems to a DMP. However, only one of these systems can be a touchscreen.

Step 3 Do only one of the following.

•Connect a USB cable to the USB interface on the back panel of your DMP. Then, connect the other end to your touchscreen.

Does your DMP model have only one USB connector? If so, you might prefer to connect an external hard drive there for added local storage. In this case, an RS-232 serial cable would be the better choice for connecting a touchscreen to your DMP.

•Connect an RS-232 serial cable to the RS232 interface on the back panel of your DMP. Then, connect the other end to your touchscreen.

Step 4 Turn On the touchscreen.

Tip Does a message on the touchscreen say that it must download a "characterization" file? This happens only when your touchscreen uses technologies from Elo TouchSystems and when you have never turned it On previously (or after its flash memory card is reformatted). When you see this message, please disregard it. The touchscreen will obtain its characterization file automatically during a later stage of DMP setup.

Connect to an Analog Display or Projector

Tip DMPs support connections to analog presentation systems. However, we recommend strongly that you use digital presentation systems whenever possible.

Before You Begin

•You must obtain and use a custom-built, third-party adapter cable before you can establish a component video connection to your DMP. The S-Video/YPbPr connector on a DMP accepts a proprietary 7-pin DIN jack. It is not likely that any mass-produced component video adapter will work on your DMP.

5. Pb (B-Y)[Component: Blue]

6. Ground

7. N/C

Procedure

Step 1 Click DMP Display Attributes in the Settings list.

Step 2 Choose Disabled from the the DMP Display Autodetection list.

Step 3 Do one of the following to connect an analog video display device to your DMP.

•Will you use S-Video or composite video?

Composite

a. Choose Composite/S-Video from the Interface list.

b. Choose an option from the Display Standard list, such as NTSC_M.

c. Adjust any other settings as needed.

d. Apply and Save your changed settings.

e. Plug one yellow jack from the RCA video cable into the CVBS interface on the back panel of your DMP.

f. Connect the free end of this cable to the corresponding interface on your presentation system.

Understand DMPDM Workflow

The typical workflow in DMPDM assumes that you will test settings before you commit to them.

Settings in DMPDM might revert to their most recent state after your DMP restarts. This occurs by design, so that you can test new settings. If your changes cause unforseen problems, you can abandon them without consequence. And, when your changes are satisfactory, you can commit to them.

•Click Apply to test new values for a condition or setting. After this click, the change takes effect. However, this change is temporary and reversible. The values that you overwrote will return the next time that your DMP restarts, unless you commit to them explicitly.

•Choose Administration > Save Configuration to store changed settings permanently. After this click, the changes persist even after your DMP restarts. When the Save Configuration page appears, you must click Save to actually save your work.

Log in to DMPDM

Before You Begin

•This procedure assumes that you connected your DMP to its presentation system, and now they are both turned On.

Procedure

Step 1 While your presentation system shows the Cisco logo and shows an IP address for your DMP, write down the IP address.

Configure Video Output

The display autodetection feature is enabled by default. However, it fails unless you use either:

•An HDMI signal cable.

•An HDMI signal cable in combination with an HDMI-to-DVI adapter.

Note Are you satisfied with the choices and entries that the autodetection feature made for you? If so, you are done with this section and you can go now to the "Protect Your DMP from Unauthorized Management" section. Otherwise, if you are not satisfied — or if your display does not support HDMI connections — do the following.

Choose and Calibrate a Touchscreen Driver

This procedure applies to you only when your DMP supports interactivity through touch and your presentation system is a touchscreen. Furthermore, it assumes that you completed the "Connect to a Touchscreen" section.

Before You Begin

•Do the hardware and firmware for your DMP support touchscreen technologies? DMP 4305G and DMP 4310G endpoints do not.

a. Check the Currently Loaded Driver row to see which touchscreen driver, if any, is active on your DMP.

The driver might be 3M, Zytronic, Elo, GeneralTouch, or possibly something else. As we test various drivers, we might update this list between any two releases.

Your DMP must use a driver that is compatible with your touchscreen.

b. If the active driver is not compatible with your touchscreen, choose the compatible driver from the Choose Touch Screen to Activate list.

c. Click Apply.

d. Click Save Configuration in the Administration list, and then click Save.

e. Click Restart DMP in the Administration list, and then click Restart.

Tip The Elo and GeneralTouch drivers are self-calibrating.

Step 6 If you chose 3M, Zytronic, or another driver that must be calibrated manually:

a. After your DMP has restarted, log in again to DMPDM.

b. Click Touch Screens in the Settings list.

c. Click Calibrate <driver_name> Screen, where driver_name is the name of the driver that you chose.

•Messages on the touchscreen prompt you to touch its surface in various places. Follow these prompts exactly. For example, the calibration utility might prompt you to touch exactly five areas or exactly nine areas.

•Time is limited. When you do not complete this exercise within the brief period that is allotted for it, the calibration utility times out automatically.

•Repeat these steps for manual calibration if the driver utility times out before you can finish.

Configure NTP Settings for Time-Dependent Features

IP-enabled devices including DMPs can use network time protocol (NTP) to synchronize themselves with radio and atomic clocks located on the Internet. Thus, the accuracy of their local time-keeping is ensured. NTP can synchronize distributed clocks within milliseconds over long time periods. You must configure NTP settings on any DMP through which you will provide:

•IPTV services with Cisco Cast.

•Proof-of-play services with Cisco Digital Signs.

•Any other service that is dependent upon accurate Start and Stop times.

•Hostname 1 — Enter the DNS-resolvable name of the network time server to use by default. This is your primary time server. Your DMP will not use any other unless this one is not available.

Note We recommend that you set the default NTP hostname to pool.ntp.org.

•Hostname 2 — Enter the DNS-resolvable name of a network time server to use whenever the primary time server is not available.

•Hostname 3 — Enter the DNS-resolvable name of a network time server to use whenever the secondary time server is not available.

Step 4 Choose from the Time Zone list the time zone that is correct and local for your DMP at its location.

Step 5 Enter in the Refresh Interval field the maximum number of milliseconds that are permitted to elapse before your DMP retrieves a fresh time stamp from its NTP server. The factory-default maximum is 17 ms.

Step 6 Click Apply to confirm and test your choices.

Your entries are recorded to volatile memory and take effect — but only until you change them or restart your DMP.

Step 7 When you are satisfied that you chose the correct settings, click Save Configuration in the Administration list, and then click Save.

Your entries take effect permanently and will persist even after your DMP restarts.

•We do not support "open" wireless networks. They are a security risk.

•Does a security policy in your network restrict DHCP address assignments to known MAC addresses? If so, locate the WLAN address printed on a sticker that is affixed to your DMP. Then, share this address with your security policy administrator.

•Verify that your wireless network is working correctly, is available, and you understand how it authenticates connection requests.

Step 3 If the DHCP server process is not running yet on the DHCP server, start that process now — along with any processes that it uses.

Step 4 Turn On your DMP and make a note of the IP address that it shows on its presentation system.

Step 5 Point your browser to the IP address.

Note Is your DMP brand-new? Or, have its settings been restored to factory defaults? If so, DMPDM prompts you to define a master password for your DMP. You must do this before you can do anything else. See the "Log in to DMPDM" section.

Step 6 When prompted to log in, use the master username and password that you defined.

Understand DMP User Accounts and Passwords

In contrast, the Service Account is a user account with FTP and SFTP login privileges. It is available only on DMPs whose FTP service is enabled.

Note Unless or until you change these passwords individually, they are both identical to the master password that you configured in the "Log in to DMPDM" section. You can change them when they should differ. However, they will become identical again in the future if you edit the master password.

Understand URI Encoding Syntax

When you enter the text string in Cisco Digital Signs to change a DMP password, that string must use the correct syntax for URI encoding.

•You must enter a plus sign (+) instead of a space wherever the value for a queryable object should contain a space. For example, if the queryable object is "user" and its value is "John Smith," you would enter "user=John+Smith" in your string.

•Do any values in the string contain an actual plus sign? If so, you must encode the plus sign explicitly as %2B.

Step 2 Enter a new duration in milliseconds in the Splash Screen Display Time (in milliseconds) field.

Step 3 Click Apply.

Step 4 Click Save Configuration in the Administration list, and then click Save.

Step 5 Stop. You have completed this procedure.

Protect Your DMP from Unauthorized Management

Caution Configure your network firewall to restrict access to DMPs over TCP port 7777. Permit such access from only the DMM appliance where your fully licensed copy of
Cisco Digital Signs is installed. If you do not know how to define an access control list (ACL), ask the security policy administrator for your network or see the manufacturer documentation for your firewall.

Note You cannot centrally manage a DMP from more than one DMM appliance (CSCto62211).

When you use Cisco Digital Signs to manage a network of DMPs centrally, you must configure each DMP to secure and trust its communication with Cisco Digital Signs.

Note Until you change these passwords individually, they will be identical to the master password that you configured in the "Log in to DMPDM" section. You can change them when they should differ. However, they will become identical again in the future if you edit the master password.

You can use DMPDM to change the DMP Web Account password and Service Account password on one DMP.

Change the Web Account Password for Centrally Managed DMPs

Note•This procedure assumes that you manage your DMPs centrally. Furthermore, it assumes that you use Cisco Digital Signs and not Cisco StadiumVision for this purpose.

•Until you change this password individually, it will be identical to the master password that you configured in the "Log in to DMPDM" section. You can change them when they should differ. However, they will become identical again in the future if you edit the master password.

All DMPs that you manage centrally must share identical user credentials for their DMP Web Account.

You can use Cisco Digital Signs to change the Web Account password simultaneously on DMPs all throughout your network.

c. Check the check box for each DMP where the DMP Web Account password should change.

d. Choose from the Select an Event Type list the system task that you named in Step 2.

e. Click Submit.

Step 7 Stop. You have completed this procedure.

Change the Service Account (FTP/SFTP) Password for Centrally Managed DMPs

Note•This procedure assumes that you manage your DMPs centrally. Furthermore, it assumes that you use Cisco Digital Signs and not Cisco StadiumVision for this purpose.

•Until you change this password individually, it will be identical to the master password that you configured in the "Log in to DMPDM" section. You can change them when they should differ. However, they will become identical again in the future if you edit the master password.

All DMPs that you manage centrally must share identical user credentials for their DMP Service Account. You can use Cisco Digital Signs to change the Service Account password simultaneously on DMPs all throughout your network.

•Servlet Server Address — If you have not already done so, enter the DNS-resolvable hostname and domain for the appliance that is serving Cisco Digital Signs, such as dmm.example.com.

Note When your entry here is neither DNS-resolvable nor IP-routable, your DMPs are prevented from loading any assets that you store on your DMM appliance.

•DMP User Name — Enter admin or, when you have changed the DMP Web Account username from the default value, enter the new username that you assigned.

•DMP User Password — Enter the password that corresponds to the username.

Step 3 Click Save.

Step 4 Stop. You have completed this procedure.

Caution DMP credentials must match exactly in DMPDM and
Cisco Digital Signs. If you ever use a system task in
Cisco Digital Signs to change DMP credentials, you must then return here and enter matching values. Otherwise,
Cisco Digital Signs will use the wrong credentials when it tries to communicate with your DMPs. Then, after communication fails, it will consider your DMPs to be unreachable and unmanageable.

Note Is the splash screen disabled? If not, you should see it on the attached presentation system soon after you start a DMP. The factory-default duration is 30 seconds. However, it might be much less in your case when anyone in your organization has changed this user-configurable setting.

Does Cisco Digital Media Manager report that your DMP is unreachable?

Can you ping the last-known IP address for the DMP?

Can you also ping any different IP address that the splash screen might have shown instead?

When your browser loads the last-known IP address for the DMP, does DMPDM start?

Check the LEDs

The DMP chassis contains a green LED and a red LED. After your DMP is attached to its AC power source, you should see light from both LEDs through the DMP front grille. The LEDs tell you when your DMP has power and when it has an IP address. To work as designed, it must have both.

Table 4 Troubleshoot with LEDs

LED Status

Troubleshooting Notes

Green

Red

On

On

Your DMP is connected to its power source and is receiving electrical power. However, it has not yet obtained an IP address to use. Your DMP should obtain its IP address within 2 minutes. When the red LED persists:

•For a wired network connection — Are both ends of the Ethernet cable plugged in?

•For a wireless network connection — Is the wireless network active?

•Does restarting your DMP resolve this problem?

•Was any IP address in effect previously for your DMP? If so, can you ping that IP address? If you do not remember what the address was, there are ways to obtain it. Turn On a presentation system that is connected to your DMP and is configured or calibrated as necessary, and then try one of these methods.

–Press Show IP on the handheld remote control unit for your DMP. Write down the IP address that the presentation system shows to you. (Remote controls for DMPs are sold separately.)

–Restart the DMP. If its splash screen is configured in DMPDM to persist for any visible duration, write down the IP address that the splash screen shows to you.

Step 2 Click Browse — or its equivalent if your browser applies a different name to this button — when the Upgrade Firmware page appears.

Step 3 Navigate to the firmware update that you downloaded, and then choose it.

Step 4 Click Start Upgrade.

Note Do not close or browse away from this page until messages in DMPDM state that your DMP has loaded the firmware image and started to burn it. Otherwise, upgrade fails.

Step 5 Stop. You have completed this procedure.

Before You Submit Any Service Request

Timesaver First, please check our DMP documentation on Cisco.com. We revise it continually and strive to answer every question. DMP documentation is always available, fully searchable, and its only purpose is to help you. See http://tools.cisco.com/squish/462c8.

Check our public support forum. Experts monitor this forum daily and stand ready to guide you past common or unusual issues with your DMPs. You can also search the support forum to learn if your questions are already answered. See http://tools.cisco.com/squish/4e32C.

Use `Bug Tool'on Cisco.com to learn what we know about any problem that affects DMPs. The entries in Bug Tool might warn against a problem's root cause, say how to work around it, or explain how to recover from it. Or, they might tell you we fixed the problem in a software patch or release. See http://tools.cisco.com/squish/106b1.

If you still want to open a service request, gather and prepare notes about your equipment and network.

· What was the last task that you performed with your DMP before you noticed the problem? · What serial number and MAC address are visible on your DMP chassis? · What was the Cisco sales order number for your DMP? · What firmware release number is installed on your DMP? · What number, if any, identifies your Cisco service contract?

DMP Restarts Unexpectedly

Q. Why would a DMP reboot itself?

A. Rather than crashing when they run low on memory, DMPs restart automatically. The restart clears their memory and causes downtime of much less than 1 minute. This momentary interruption is prefereable to the lengthy downtime that a hard crash would cause.

Tip In the rare case that a DMP does run out of memory and restart automatically, a SWF asset is almost always responsible. Our content creation guidelines on Cisco.com explain how to optimize SWF assets for DMP playback.

DMP Reset Button

Q. What are the purpose and correct use of the Reset button on my DMP?

A. You can use the Reset button in either of two different ways (CSCth71099).

•Restart (reboot) your DMP — Press the Reset button and release it immediately. Your DMP should beep one time (unless it is a DMP 4310G, which does not beep), and then restart.

•Erase all DMP settings — After you press and hold the Reset button for at least 10 seconds, your DMP should beep two times (unless it is a DMP 4310G, which does not beep). You have erased every setting and restored Cisco factory-default settings to the firmware on your DMP. You must configure it as you would configure a factory-new DMP.

Q. When I erase DMP settings, are its local storage volumes (internal and USB) erased, too?

A. No. They are not erased.

DMP Use of Power-over-Ethernet

Q. What will happen if I try to use AC power and PoE simultaneously on a DMP?

A. When both PoE power and AC power are detected, AC power overrides PoE and disconnects the PoE circuit.

Q. Does my use of PoE affect the operation of any other DMP feature?

A. A DMP 4310G has two USB interfaces on its chassis. When you use PoE to power a DMP 4310G, we recommend that you use no more than one of these USB interfaces at a time. IEEE 802.3af PoE is limited in its capacity and might not be sufficient to power your DMP and two USB peripherals simultaneously.

DMP Audio Playback

A. Make sure that your DMP has attributed an authentically HDMI-standard resolution value — such as "HDMI_1080p60" — to your presentation system (CSCsk29797). The HDMI standard does not support audio playback through any system whose settings ignore or contradoct HDMI standards. Thus, you cannot use HDMI to play audio through a presentation system whose resolution setting is, for example, "VESA_1360x768x60."

DMP Remote Control

Q. How can I improve the effectiveness of a DMP remote control?

A. Compensate for known factors.

Check the battery

Is a battery present?

Is it installed correctly?

Is it fully charged?

Check the DMP mount

Your DMP is equipped with an infrared (IR) sensor that receives, recognizes, and reacts to the signals from a DMP remote control.

However, the way that you mount your DMP can limit how well it responds to these signals. For example, the mounting method might block the IR sensor. This in turn might cause you to attach an IR extension cable to your DMP, as a workaround.

But even when you mount the receptor from this extension where it is not obstructed — and even though this method improves the reception of IR signals that are blocked otherwise — IR extension cables are not perfect. The physics that underlie their design ensure that these cables always have some signal loss,

Furthermore, greater cable length contributes greater signal loss. Thus, the field (angle) of transmission becomes narrower for a remote control and the range (distance) becomes shorter in direct proportion to the length of the IR extension cable.

Check for sunlight

Prevent sunlight from shining directly on your DMP's IR sensor. And take further steps as needed to stop halogen bulbs from shining at the sensor.

DMP-attached Touchscreens

Q. What can cause a properly calibrated touchscreen to operate as if it is not calibrated?

A. If this happens to you, unplug the serial cable (or USB cable) that connects this touchscreen to your DMP. Then, plug that cable back in again.

DMP Network Connections

Q. What prevents me from centrally managing my DMP?

A. Ask yourself these questions.

•Has your DHCP server changed the IP address assignment for your DMP?

•Was your DMP running when its address changed?

If these statements are true, do not wait for your DMP to restart automatically. Instead, restart it manually. Until it is restarted, it cannot be centrally managed.

Q. Can I use a wireless DMP model as an access point for other devices?

A. No, not in this release.

Q. Which IP address is active on my DMP when its Ethernet and 802.11 interfaces are both connected?

A. Ethernet connections take priority over Wi-Fi connections on DMPs where both are active.

Q. Does a DMP 4305G support Wi-Fi?

A. No.

Q. Does a DMP 4310G support Wi-Fi?

A. No.

Q. What might prevent my DMP from receiving an IP address on a wireless network?

A. These are among the possible reasons.

•The Broadcast SSID setting must be enabled on your wireless access points. Is it enabled?

•You must reconfigure your wireless DMPs whenever you change SSID settings in your WLAN. Did you forget to do this?
